There is also a game type drop down menu, maybe you have changed it to omaha (if you don't play it then nothing will also show up also)? Then if nothing shows up and you are sure there are no filters on, or dates or anything else then I'm out of ideas.

i had a lot of problems with tournament results. profits and ev were wrong and sometimes same thing as u happened to me. i just pressed "stats" and then press "default stats" and that worked. anyways i switched back to HM1. 1000 times faster, better and simplier.
